' relation.

Heretofore, the material of this character which has been most commonly used has had brick-simulating designs applied thereto. It will be obvious that in such material all of the brick simulating faces are of the same size, and these .faces are arranged in horizontal courses vertically staggered. It has been possible in the use of this material to efl'ectively conceal the panel character thereof when applied to a wall by wire cutting certainof the brick simulating faces in the manner set forth in the Fried patent, No.

Recently, attemptshave been made to develop an acceptable siding material of this character having applied to the face thereof a design simulating random-laid stone work, wherein the stone s mulating faces are of various sizes and shapes. For best and most economical applications of such material, the panels'must be applied to a building in horizontal courses with the panels in adjacent courses horizontally offset or staggered. Certain conditions arise in connection with this stone-simulating material which have not been present in the brick-simulating type of. material. Thus, whereas the continuity of horizontal joint lines in a brick simulating siding presents no problem, because brick work is normally laid in horizontal courses so that the mortar joint simulating lines may coincide with the horizontal joints between panels to conceal said joints. no sueh assisting factor occurs in random-laid stone work. In consequence, all of thestone simulating siding of this character with through the horizontal aligned application of the panels, serves to produce in the material as applied, a series of continuous mortar joint simulating lines coinciding with the joint lines between the panels and extending uninterrupted for the horizontal dimension of the building wall. These continuous lines are very noticeable, especially when viewed at an acute angle, as when a person standing on a side walk in front of a building having the material upon its side wall looks at one of the side walls. The random size and random arrangement of the stone faces upon the siding results in a very definitely discontinuous or broken effect in all of the horizontal mortar joint simulating lines except those occurring at the margins of the abutting courses, and hence these marginal joint lines stand out very prominently and definitely expose the panel character and thecourse arrangement of panels on the wall.

It is the primary object of this invention to modify the appearance of siding material simulating random-laid stone work in such a manner as to camouflage the horizontal joint lines at the margins of the constituent panels, and thereby provide in a wall covered with this material no continuous or uninterrupted horizontal mortar joint lines.

remain the continuous horizontal joint lines between the adjacent courses of material which,

A further object of this invention is to provide siding material which closely simulates the appearance of awall formed of natural randomlaid stones, when applied in horizontal courses to a wall.

A further object of. this invention is to provide siding material which presents the appearance of stones of random size and random shape laid upon a wall, and alsogives the appearance of Fig. 3 is a perspective view of a unit of my improved siding material.

Fig. 4 is a vertical sectional view taken on line 4-4 of Fig. 3.

Referring to the drawing, which illustrates the -preferred embodiment of the invention, the

numeral l designates a rectangular panel of rigid composition board, such as Celotex or Insulite. At one horizontal and one vertical edge of this panel inset ship lap flanges H are formed, while at the two opposite edges thereof complementary flanges I2 are formed by undercutting as is well understood in the art. These panels-with the shiplap flanges H and H are adapted to be applied to a supporting structure in coplanar relation with the interlocking ship lap flanges II and i2 serving to form a water tight joint between the panels. A protective and decorative coating I3 is applied to one face of eachpanel ID. This coating may be of any con.- ventional character such as a coating of asphalt in which is partially imbedded a continuous surfacing layer of comminuted masonry particles, such as small stone granules, grit, or the like. It will be understood that it is conventional to employ a coating wherein the color of the surfacing granules closely approximates the color of the stone being simulated, and that a blend of colors may be employed if desired.

A- plurality of horizontal mortar joint simulating depressions H and vertical mortar joint simulating depressions I! are formed in random arrangement upon the face i3 of the panel. These depressions I4 and I! may be of any desired character to simulate the mortar conventionally used between the stones in a stone wall. Commonly, these depressions constitute elongated areas of narrow width at which the granular coating is completely imbedded within the underlying coating of asphalt to conceal said granular material and to provide a contour simulating a raked mortar joint common in masonry. However, it will be understood that the mortar joint simulating lines l5 may be of any desired character, such as areas at which the grit differs in color and/or texture from the grit upon the remainder of the panels; or areas at which only a part of the granules is imbedded completely within the asphalt coating. The mortar simulating lines If preferably extend horizontally and in parallel relation to the upper and lower edges of the panels, while the mortar simulating lines l5 preferably extend vertically. The mortar simulating lines I4 and I! are so arranged on the panelas to define between them a plurality of faces "5 of various sizes and in a random arrangement.

At one horizontal margin of'the face of the panel Ill, here shown as the top edge, I provide a marginal mortar simulating line I! which extends for the major portion of the length of the paneland is interrupted by a stone simulating face i8 which extends to the edge of the panel. At one vertical edge of the panel, here shown as the right edge of the panel, I. provide a marginal mortar simulating line l9 which is interrupted by one stone simulating face 20. In the preferredform, as illustrated in Fig. 3, at least one portion or each of the marginal mortar simulating lines I1 and I! bounds two or more of the stone simulating faces II. A stone simulating face 2| of the same width as the face II is formed at the horizontal edge of the panel'opposite face i8 and is laterally offset fromface 2|.

A stone-simulating face 22'of the same height and horizontally aligned with face 20 is formed at the margin of the panel opposite face 20. The faces I! and 2| are each provided with a plurality of narrow elongated shallow indentations or depressions 22 extending in spaced horizontal relation- Similar indentations 24 in spaced parallel vertical arrangement are formed in the faces 20 and 22. The indentations 23 in faces I. and 2i are preferably spaced apart a dimension corresponding to the width of the mortar Joint H. The indentations 24 on the face 20 and 22 are spaced apart approximately the same distance and substantially equal to the width of the mortar joint i9.

It will be observed from Figs. 1 and 2 that when panels constructed as above defined are laid up on a wall in horizontal courses, the horizontal joint lines 11 at the margins of said courses are effectively concealed. This occurs by virtue of the fact that the faces I8 and 2i are placed in register and abut each other, so as to present the appearance of a continuous stone which spans the joint line H. The indentations 23 serve to complement the joint crevice between the faces of the abutting panels to camouflage the same. At the same time, the spaced relation of the indentations and occurrence of the bars of granule-coated surface between them, give the appearance of a random-laid textured stone having slightly different color from, but one which definitely blends with the color of the other stone faces it. The same effect is achieved by the abutting faces 20 and 22, which serve effectively to conceal the vertical joint lines between adjacent abutting panels. However, it will be noted that the face formed by elements 20 and 22 'gives a different appearance and a different texture from that formed by the face elements I 8 and 2|, which texture and appearance however definitely blends with the faces i6 and faces l8 and 2|.

In order to obtain an effective blending of the faces 20 22 and I82l, with the random effect of the remaining faces l6, it is preferred to form said faces so that portion 20 is of substantially greater width than portion 22 and portion 18 is of substantially greater length than portion 2|, whereby the division of said stones .at joint lines and between the mortar simulating lines I! and I9 bounding said composite faces, will be off center. It has been found that this arrangement works very satisfactorily and produces a very natural appearance.
